Inorganic compounds containing the −C≡N group are not called nitriles, but cyanides instead.105-34-0, formula is C4H5NO2, Name is Methyl 2-cyanoacetate. Though both nitriles and cyanides can be derived from cyanide salts, most nitriles are not nearly as toxic. Reference of 105-34-0.
Manel, Augustin;Berreur, Jordan;Leroux, Frederic R.;Panossian, Armen research published 《 Electrophilic fluorosulfoxonium cations as hidden Bronsted acid catalysts in (n + 2) annulations of strained cycloalkanes》, the research content is summarized as follows. The highly electrophilic fluorosulfoxonium cation [Ph2S(O)F]+[B(C6F5)4]- was shown to promote (n + 2) annulation on donor-acceptor (D-A) strained cycles. This study highlights new reactions catalyzed by highly electrophilic sulfoxonium cations and the thin barrier between Lewis acid catalysis and Bronsted acid catalysis.
Reference of 105-34-0, Methyl cyanoacetate is an alkyl cyanoacetate ester.
Methyl cyanoacetate is the intermediate product in pharmaceutical organic synthesis as well as in the synthesis of some biologically active compounds used in agriculture. It undergoes calcite or fluorite catalyzed Knövenagel condensation with aromatic aldehydes, giving the corresponding arylidenemalononitriles and (E)-α -cyanocinnamic esters.
Methyl Cyanoacetate is often used as a nucleophile in the electrochemical oxidation of catechols. Methyl Cyanoacetate is also a reagent in the synthesis of Methyl 2-Amino-4-trifluoromethylthiophene-3-carboxylate (M287290); a compound used in the synthesis of DPP-IV inhibitors for treating type 2 diabetes., 105-34-0.
